So Takumi left her in Kaguya's care.
Kaguya didn't refuse the taskin fact, she eagerly took Tsukasa away.
She really was interested in her.
Takumi didn't pay much attention to Tsukasa afterward. Her world didn't hold much appeal for him.
To Takumi, it was just an ordinary worldeven if Tsukasa was immortal.
So after a brief chat, he passed her to Kaguya.
Immortality?
Takumi had that too.
In fact, his world even sold immortality pillsthe Hourai Elixir.
The research institute had developed it long ago, led by Eirin Yagokoro.
Many nations were very interested in this medicine.
After all, it granted immortalitysomething humanity had always dreamed of.
But Takumi hadn't released it to the public.
Only some life-extending drugs had been distributed so far.
The Hourai Elixir might never be made public.
It would probably be reserved for private use only.
People like Ningguang, for instance, were considered for it.
Ohand Bronya.
Thinking of Bronya, Takumi figured it might be time to let her take the Hourai Elixir.
Keeping her at her peak forever wasn't a bad idea.
Though her lifespan was already long, who would say no to a longer one?
He'd talk to her about it later.
Before that, Takumi decided to head to the research institute and pick up some Hourai Elixir.
With that thought, he vanished from his spot.
He arrived at the medical research division of the institute.
The person in charge there was none other than Eirin Yagokoro.
She was deeply passionate about pharmacology.
Especially after Takumi's world had integrated knowledge from many others, she became completely obsessed.
She didn't even bother with Kaguya anymore.
As she put it: that little cabbage's already been claimedand by her superior no lessso why should she care?
Besides, she couldn't control Kaguya.
Kaguya had become much stronger.
With the chat group's help, she now surpassed Eirin in strength.
So what was the point of managing her?
Let her do as she pleased.
As for her image? Princesses didn't need image.
Let her be as outrageous as she wanted.
Eirin would focus on her research.
Thus, she became the head of the pharmaceutical institute.
Many of Takumi's world's medicines were developed by her.
Of course, there was also Mobius.
Though they worked independently, the two often exchanged ideas.
Like nowwhen Takumi entered Eirin's office, he saw Mobius there as well.
The two were deep in discussion.
Takumi walked right in.
Their senses were sharpupon sensing Takumi's arrival, they both paused.
Eirin stared at Takumi, full of question marks.
Why had he come? Was he looking for her specifically?
If not, he wouldn't have come to her office. Normally, if he wanted someone else, he'd go to their own office.
"What are you doing here~?"
Mobius raised an eyebrow and stared pointedly at Takumi.
"Did something stop working? Is that why you're here for meds?"
She suspected he was here for... performance issues.
"Probably not,"
Eirin added.
"The princess said this guy's like a beast. Doesn't seem like someone who'd need that kind of medicine."
That was what Kaguya had said, and Eirin couldn't see any weakness in him either.
So that couldn't be it.
"You two done talking yet?!"
Takumi cursed inwardly.
Kaguya was spouting nonsense again.
"You're the beast! Your whole family's beasts!"
"Then why are you here?"
Mobius shrugged, dropping the subject and getting to the point.
"I came to pick up some Hourai Elixir. And you? What are you doing here?"
Takumi stated his purpose and eyed Mobius curiously.
"I'm here discussing things with Eirin, of course. You want Hourai Elixir? Doesn't that stuff not work on you?"
Mobius was puzzled.
Takumi already possessed immortalitywhy would he need the elixir?
"It's probably for someone else,"
Eirin replied.
"For you. The version we made before, I've improved it. Now, after consuming it, you'll gain the Hourai constitution without being locked out of power growth. This is the complete version."
She guessed correctlyit was for someone else.
So she didn't ask further and took out the improved Hourai Elixir.
Chapter 514: Prometheus Doesnt Want to Tell You
The earlier versions of the Hourai Elixir were incomplete.
When Kaguya took it, her strength plateaued at a certain level and stopped improving. In essence, it stifled her future potential.
Eirin experienced the same limitation.
They had gained immortalitybut lost their path forward.
Because of that, after Kaguya underwent enhancements via the chat group, Eirin took some of her blood samples for further research.
She then improved the original Hourai Elixir, eliminating all side effects.
In theory, with the new version, the longer you lived, the stronger you could become.
Since Takumi needed it, Eirin gave it to him without hesitation.
Takumi accepted the porcelain flask she handed him.
"Good! You two carry on."
With the elixir in hand, he had no desire to interrupt the two mad scientists any further.
"Wait!"
Just as Takumi was about to leave, Eirin stopped him.
He turned, puzzled. "What is it?"
Was there more?
"Please have a child with the princess. I'm very curious what kind of offspring you two would produce."
She was completely serious.
Since Takumi and the princess were already together, she felt it was time for them to have a child.
Mobius's eyes lit up as well.
"That's actually a good idea. I'm curious too. But the stronger the parents, the harder it is to conceive."
"I bet you two don't use any precautions, right? That could be why you haven't had kids."
"If it turns out you really can't have a child, you can come to me. I wouldn't mind helping."
Mobius looked visibly excited.
Right now, what she wanted most was to study Takumi's future child.
She was dying to do research.
But it seemed unlikely. Maybe she thought she should just step in personally?
Hearing her suggestion, Takumi rolled his eyes.
This womanwas she not embarrassed at all saying these things?
Fine, if you're shameless, I'll be shameless too.
"Alright. I'll visit you tonight."
The room fell silent.
Eirin and Mobius both froze.
He was serious?
But Mobius quickly regained her composure, giving Takumi a mischievous grin.
"Sure~! You better remember. If you don't show up, you're a coward."
She wanted to see if he was all talk.
Eirin's eyes gleamed with intrigue.
Goodness, was Mobius trying to trap Takumi?
And if he really did show upthen what?
Takumi was puzzled too. But there was no way he was backing down now.
"Alright, alright. Just wait, future baby mama!"
You want to play? Don't regret it later.
With a scowl, he left the lab.
He had made up his mind. Tonight, he would find out if Mobius's mouth was the only thing she had that was tough.
Let's see how she handled something tougher.
He wasn't going to lose anything by trying.
After Takumi left, Eirin couldn't help but sigh.
"You were serious about this?"
Mobius snorted.
Though she was a little nervous, her words stayed bold.
"I don't think he'll really come. Even if he does, I'm not afraid. Maybe I'll finally get the data I've always wanted."
"I've always wanted to research him. The rest of the Genius Society does too. They're all eager to study Takumi."
Stay calm. Don't panic.
Eirin rolled her eyes.
She understood perfectly. Takumi's very existence was like a drug to researchersirresistibly fascinating.
Mobius was no exception.
Maybe she was secretly hoping he really would show up.
But Eirin didn't call her out.
...
Takumi returned home, still irritated.
He wasn't in a good mood.
He'd already decidedMobius was getting what she asked for.
But first, he had other things to take care of.
He found Bronya upstairs, playing video games.
He pulled out the Hourai Elixir he brought back.
Bronya looked at him, puzzled.
"What's that?"
"Hourai Elixir. Take it."
Takumi didn't explain much. He simply handed her a pill.
He had some of the old versions on hand, but he wouldn't give those to Bronya.
That's why he went to get the new formula from Eirin.
Bronya hesitated briefly but didn't ask questions. She quietly took the elixir.
She understood Takumi's intention. There was no need to say anything.
Soon after, she felt the changes in her body.
Some things she thought were gone... had returned?
Feeling the difference, her cheeks turned pink.
"It's really that strong?"
Everything had come back.
Takumi gave her a smug grin. "Impressive, right?"
Bronya tossed her controller aside.
"No more games. Let's go enjoy ourselves!"
"Just like before..."
Takumi's face lit up with a smile.
After a round of nostalgic fun with Bronya, Takumi called Miori Shiba and Liliya back.
He gave them each a dose of the elixir as well.
Gabriel and Esdeath, who was still out fighting in space, would also get theirs later.
Takumi wasn't going to play favoriteseveryone would get one.
Except Kaguya. She already had hers.
After all the running around, it was already nighttime.
As evening settled in, Takumi slipped away.
Everyone found this strange.
Bronya quickly asked, "Where are you going?"
Takumi casually replied, "I'm going to teach Mobius a serious lesson. Damn it, she disrespected me!"
With that, he dashed off.
The others were stunned.
He was going to teach Mobius a lesson?
What had happened?
"Prometheus, what's going on? Do you know anything?"
When in doubt, they turned to Prometheus.
But this time, Prometheus remained silent.
Chapter 515: Gabriel Wants to Quit the Group
Bronya grew even more confused when Prometheus didn't respond. But slowly, she figured it out.
Takumi was going to Mobius's place for the night!
"Teach her a lesson?" she thought. Got it!
She couldn't help but mentally complainwhat exactly did Mobius do to make Takumi fixate on her like that?
A lesson she'd never forget, huh? Yeah... unforgettable for life.
Well, if she took the Hourai Elixir, she could relive that lesson often~
Bronya shook her head. Another new sister, huh?
The others quickly understood the situation too but didn't say anything. Everyone already knew Takumi was an SP.
Through the network, Takumi learned that Mobius had returned home from work and was alone.
Seeing no issues, he immediately rushed over.
Mobius was stunned to see Takumi suddenly appear in her house.
"You're seriously here?!"
Her face turned pale. He actually came?
Takumi smirked. "Oh~!" She looked panicked now.
Just as he thoughtMobius's bark was worse than her bite.
...
Takumi thoroughly put Mobius in her place, teaching her that talking big doesn't always end well.
But Mobius was the kind who liked to play hard-to-get and didn't learn easily.
Takumi also discovered that she had taken the Hourai Elixir too.
That made things interestingbroken and healed, healed and broken. A perfect loop.
After sorting Mobius out, he resumed his responsibilities.
He traveled to space and gave Esdeath the Hourai Elixir.
After spending some time with her, he returned to Earth to continue his work.
Esdeath's forces were making excellent progress, conquering several alien civilizations.
In fact, the outer space regions were starting to unite, seemingly preparing to face Esdeath's army.
But thanks to the mechanical species, Esdeath's army was nearly infinite. She could even mass-produce soldiers if needed.
Because of that, Takumi decided it was time to migrate another world.
This time, it would be Gabriel's.
Gabriel had returned for some time already, so it was about time to bring her world over too.
The marker had long been placed. Now he just needed to go and initiate the process.
Without hesitation, he tagged Gabriel in the group chat.
Takumi: [@Gabriel, I'm heading to your world now.]
Gabriel saw the message and instantly frowned. Was he trying to mess with her again?
Gabriel: [Don't come!!] [Why are you coming?!]
Clearly, she was still mad about how Takumi had previously brought Gabriel over without warning.
Now he was coming personally? It screamed trouble.
Takumi: [???] [I'm literally coming to transfer your world.] [Did Satania infect you?]
Seriously, what was with that overreaction?
Takumi didn't even know how to respond to her suspicions.
Gabriel: [Oh, that's why. Fine, come over.] [Actually, Vignette is at my place too.] [I'll introduce you to a demon.]
Once she realized he was there for a legitimate reason, she didn't argue further.
Takumi had already mentioned this before.
She just thought he was coming to cause trouble.
Last time, her older sister scolded her over what happened, and she was still upset about it.
Takumi: [A demon? I already know her!] [@Akeno, allow me to introduce Gabrielshe's not just a demon, she's a fallen angel too!] [Technically, you two are alike.]
Fallen Angel Gabriel. Though technically an angel, she acted more like a demon.
Just like Akeno, who was also a fallen angel, a demonand a generous one at that.
Nothing wrong there.
Akeno: [Ara~! Didn't Gabriel know? I'm a demon, you know!]
Gabriel: [Now I do!!] [Fine, I'll introduce you to a beautiful girl instead!]
Emm...
Seeing these messages, Gabriel found the whole thing annoying.
So she just changed her pitch and decided to introduce a beauty instead.
Kaguya: [Is she prettier than me?]
Bronya: [Prettier than me?]
...
There's no way to have a normal conversation here.
I'm quitting the group. I'm done! (??Ў)
Gabriel was fuming at all the killjoys in the chat.
Takumi: [Haha~!] [Not chatting anymore.] [After transferring your world, I need to work on Tsukuyomi's world too.]
Takumi dropped the message in the group and started preparing for the transfer.
He activated his magic and began teleporting.
Gabriel's world was decently stable, so he wasn't too worried about overwhelming it.
Still, he suppressed his aura just in case. He had never been there before, after all.
In an instant, Takumi vanished from his home.
When he reappeared, he found himself inside Gabriel's apartment.
"So annoying!! What a pain, why does he have so much going on? I really want to leave the group..."
